Description

Technical Field

[0001] The utility model relates to the agricultural field, in particular to the technical field of garlic harvesting, and specifically refers to an adjustable garlic harvester. Background Art

[0002] Garlic is a perennial herbaceous plant of the genus Allium in the Liliaceae family. It is divided into hard-leaf garlic and soft-leaf garlic. The most common garlic in China belongs to the hard-leaf garlic. It is usually composed of many fleshy, petal-shaped small bulbs arranged closely, and the outside is covered with several layers of white to purple membranous bulb skin. Garlic has a string-like shallow root system, no taproot, and the main root group is distributed in the soil layer within 5~25cm, with a horizontal diameter of 30cm. In plant morphology, the bulb itself is developed from a modified branch, and its internodes are shortened to "bulb disk". The base and edge of the stem disk are attached to the root system, and the upper part grows the original body of leaves and buds. After the differentiation of flower buds, the top bud forms a flower stalk, and the lateral buds swell to form garlic cloves. Garlic reproduces asexually, and the reproductive organ is a lateral bud on the mother body, that is, a bulb bud. A mature garlic plant consists of roots, pseudostems, leaves, flower stalks, bulbs, etc.

[0003] Traditionally, garlic harvesting mainly relies on manual labor. With the continuous advancement of science and technology, more and more agricultural machinery has replaced manual labor and reduced labor intensity. However, the existing garlic combine harvesters have a single structure and function, and the processing of garlic still requires manual participation. Utility Model Content
